Abstract
The invention relates to a press fitting tool for a hydraulic pump gear bearing of a diesel engine. The press fitting tool is provided with a pressure rod body and a positioning block, wherein the upper part of the pressure rod body is provided with a handle, the middle of the pressure rod body is provided with a pressure plate, the lower part of the pressure rod body is provided with a positioning rod, and the upper part of the positioning block is provided with a positioning convex platform. The press fitting tool is simple to manufacture, convenient to operate and good in generality, and can be used for correctly, stably and quickly press fitting the bearing, thus improving the press fitting efficiency and guaranteeing the press fitting quality.
Description
Technical field
The present invention relates to the erecting tools of diesel engine part, specifically diesel engine hydraulic pump gear bearing press-mounting tool.
Background technology
Hydraulic pump gear is important part in the transmission of diesel engine gear train.The quality of hydraulic pump gear bearing press mounting quality directly has influence on the transmission of whole diesel engine gear train.When press-fiting the hydraulic pump gear bearing, because the instrument that uses is undesirable, tend to cause the bearing deviation of being pressed now, press-fit the backgear chamber and abnormal sound occurs, affect diesel engine performance.Even, can damage bearing by pressure, cause unnecessary loss.
Summary of the invention
The objective of the invention is to design a kind of satisfactory instrument, can steadily, correctly be pressed into bearing, guarantee the installation quality of bearing.
The present invention realizes purpose of design like this.
Make cylindrical depression bar body 9 and truncated cone-shaped locating piece 8.So that the top of depression bar body 9 is with the handle 1 of neighboring annular knurl; The middle part is with pressing plate 2; The bottom is with the backstay 3 that can make with splined hole 6 matched in clearance.So that the top of locating piece 8 is with the positioning boss 7 that can make with splined hole 6 matched in clearance.
During use, the positioning boss 7 of locating piece 8 upwards is well placed, the splined hole 6 of gear 5 one ends is enclosed within on the positioning boss 7, again bearing 4 is enclosed within the bearings mounted position of needs on gear 5 tops, then backstay 3 is inserted in the splined hole 6 of gear 5 upper ends, so that the upper surface of bearing 4 is pressed close in the lower surface of pressing plate 2, slowly be pressed into from handle 1 upper end with hydraulic press.Behind the bearing press mounting on gear 5 tops, gear 5 two ends are exchanged, press-fited another bearing 4.
The present invention since the splined hole 6 that gear 5 two ends are arranged respectively with the matched in clearance of positioning boss 7 and backstay 3, play the supplemental support effect, the assurance steady positioning.Can so that bearing 4 by correctly, be pressed into reposefully, deviation can not damaged by pressure yet.
Description of drawings
Fig. 1 is structural representation of the present invention.
OnSequence number among the figure: handle 1, pressing plate 2, backstay 3, bearing 4, gear 5, splined hole 6, positioning boss 7, locating piece 8, depression bar body 9.
The specific embodiment
Below in conjunction with accompanying drawing, a non-limiting examples is illustrated.
Make cylindrical depression bar body 9 and truncated cone-shaped locating piece 8.So that the top of depression bar body 9 is with the handle 1 of neighboring annular knurl; The middle part is with pressing plate 2; The bottom is with the backstay 3 that can make with splined hole 6 matched in clearance.So that the top of locating piece 8 is with the positioning boss 7 that can make with splined hole 6 matched in clearance.
Use the present invention, during pressing bearing 4, correct, steady, quick.Can raising press-fit efficient, guarantee to press-fit quality.
